When using PM motors, it is recommended to use brake resistors.
Parameter 1-41 Motor Angle Offset
Table 96: Parameter 1-41 Motor Angle Offset
1-41 Motor Angle Offset
Default value: 0
Conversion index: 0
This parameter is only active when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM (permanent magnet motor).
Enter the correct offset angle between the PM motor and the index position (single-turn) of the attached encoder or resolver. The
value range of 0-32768 corresponds to 0–2 x pi (radians). To obtain the offset angle value: After drive start-up, apply DC hold and
enter the value of parameter 16-20 Motor Angle into this parameter.
Parameter 1-44 d-axis Inductance Sat. (LdSat)
Table 97: Parameter 1-44 d-axis Inductance Sat. (LdSat)
1-44 d-axis Inductance Sat. (LdSat)
Default value: Size related
Conversion index: -6
This parameter corresponds to the inductance saturation of Ld. Ideally, this parameter has the same value as parameter 1-37 d-axis
Inductance (Ld). If the motor supplier provides an induction curve, enter the induction value at 200% of the nominal value.
Parameter 1-45 q-axis Inductance Sat. (LqSat)
Table 98: Parameter 1-45 q-axis Inductance Sat. (LqSat)
1-45 q-axis Inductance Sat. (LqSat)
Default value: Size related
Conversion index: -6
This parameter corresponds to the inductance saturation of Lq. Ideally, this parameter has the same value as parameter 1-38 q-axis
Inductance (Lq). If the motor supplier provides an induction curve, enter the induction value at 200% of the nominal value.
Parameter 1-46 Position Detection Gain
Table 99: Parameter 1-46 Position Detection Gain
1-46 Position Detection Gain
Default value: 120%
Conversion index: 0
Adjusts the amplitude of the test pulse during position detection at start. Adjust this parameter to improve the position measure-
ment.
